CALGARY Alberta Premier Jason Kenney announced new limits on outdoor gatherings Tuesday, reducing the allowable number in a group from 10 to five, while also announcing restaurant patios will close at the end of business Sunday and remain shut for at least three weeks. University of Alberta Immunologist Dr. Lynora Saxinger says the reality is many patios are not much safer than being indoors. “You have a patio that has very, very tall partitions with an open top. And you know, people are sometimes clustered quite closely together in that space, I would consider that space not really truly what we mean by an outdoor space,” she said.
